An Apple a day keeps the viruses away?

If you’re one of the planet’s approximately 1.6-billion Microsoft Windows users, then chances are you’re pretty used to viruses. They come at you from every angle — email, websites, flash memory sticks — and if you’re sensible you have some sort of anti-virus chugging away in the bottom right-hand corner of your screen.

That’s never been true of Apple’s Mac range. Ask many seasoned Mac fanatics about anti-virus software and they will snort: “Macs don’t get viruses, man, everyone knows that”. But that changed earlier this month when one of the first Mac viruses was discovered “in the wild”.

I say “virus” but to be strictly correct it falls into the broader category of malicious software (or “malware”). Unlike a virus It doesn’t spread secretly and automatically by hijacking communications between users. Rather it relies on the user giving it permission to do its dirty work.

But who would give it permission in the first place? That’s the whole trick: the malware masquerades as anti-virus software called Mac Defender. It lies in wait on fake websites built specifically to attract Mac users and, when they visit the site, “warns” them that their beloved computer is infected with a virus. When, in a panic, they click any of its buttons, the malware installs itself.

Luckily this particular malware is fairly benign, simply nagging you to supply it with credit card details to “register” it and refusing to remove the threats it has “detected” until you do so. Unless you supply those details you are in little danger of losing anything. If you have given it your credit card already then for goodness sake get it cancelled immediately.

Although it took three weeks, Apple has now issued instructions on how to remove the malware. That seems pretty slow, but is still extraordinary. If Microsoft had to do that for every Windows based virus, they would get nothing else done. That’s why the PC security business is worth tens of billions of dollars — a lot of people need a lot of help, constantly.

The only entertaining thing about this development is the ensuing cat fight between the Mac devotees on the one hand and the Windows loyalists on the other. Just before news of the infection surfaced, Ed Bott — a perenial Microsoft booster — warned that “serious malware” was about to hit the Mac world. John Gruber — an even more staunch Apple supporter — scoffed at this idea.

In Gruber’s defence (and bad timing aside) this same refrain has been heard for literally decades and has never borne any of its poisoned fruit. There have been breaches here and there, but Apple has always moved quickly to seal them.

What’s different this time? It may simply boil down to market share. For decades Macs accounted for less than 2% of the world’s market for computers, now they account for nearly 8% worldwide and nearly 14% of the developed world, and that number is growing rapidly.

Creating malware is a skilled and time consuming process, and virus architects want a decent pay off (either monetary or ego boosting). Why aim at two percent of computer users when you can aim at 90% of them?

The internet is also vital component in this security breach. As the world of computing has become more interconnected, so these threats have become global. This merely mirrors our physical reality. The first truly global plague was the flu epidemic of the 1920s. Why? Because rapid intercontinental travel had become relatively common place for the first time in history.

But, as Gruber points out, this isn’t really a virus at all. It relies on the ignorance and credulity of users — factors that no amount of anti-virus technology can ever cure.

Will a “true” virus ever hit the Mac world, one that spreads like the biological plague it was originally named for? Mac lovers are still dismissive of this idea. They argue that, user stupidity aside, Macs are simply better built and that makes them immune to infection.

As a besotted Mac owner I’d like to believe them. The cult of Jobs is an alluring one, and it’s always tempting to feel superior to your fellow man. But writing an operating system completely invulnerable to viruses is like building a bank that’s impossible to rob.

Everyone knows the money is there and even if they have to resort to hijacking armoured cars or holding the bank manager’s family hostage, motivated thieves will find a way in. Up until now Apple’s bank has been small, safe and well staffed enough to avoid being knocked off. But, given that they were recently crowned “biggest technology company in the world”, the honeymoon is probably over.
